About

Any nourishing substance that is eaten, drunk, or otherwise taken into the body to sustain life, provide energy, promote growth. Questions with this tag should be about the historical practices of growing, preparing, and eating food, or about the historical origins of modern foods.

Food is any substance containing nutrients--in particular carbohydrates, proteins, and fats--that can be ingested by a living organism and metabolized into energy within the body, or substances that aid in this metabolism. [Food] can refer to both solid and liquid nutrition, though it often only refers to solids.

Use the [medicine] tag instead for substances used for primarily medical purposes.

Questions with this tag should be about the historical practices of growing, preparing, and eating food, or about the historical origins of modern foods. Questions solely about the modern use of food with no historical component are off-topic on this site.
